No bitcoin will never die,since most of the people are like BTC as a currency and earning purpose.
May be It can be possible if the BTC faces a perfect competitors in crypto world. So the crypto currency will,not,die
It absolutely could die.. As much as I hate to say it. If there's coins with things that Bitcoin can not do, looking into the future Bitcoin falling to 0$ is a high probability. Ethereum, not so much IMO.
